The paper presents a proposal of methods for monitoring the species Streptocephalus torvicornis, which belongs to large branchiopods. This species occurs in small ephemeral water bodies. Currently, there is only one known locality of S. torvicornis in Poland. Many species of large branchiopods are considered to be in danger of extinction. Their observation in the environment is hampered by the periodic nature of the occurrence of adults. The proposed method of population status assessment is based on the analysis of soil samples in terms of the presence of persistent cysts. The following factors may be used to assess the condition of the habitat: the presence of vegetation indicating the astatic or ephemeral nature of the pools, the level of succession of trees and shrubs, the presence of fish, the presence of potential sources of pollution. The proposed methods are universal and can be applied to the monitoring of other large branchiopods species. Regular monitoring may contribute to the recognition of other places of occurrence and will enable effective protection of the species S. torvicornis in Poland.
